Optimization of the concrete through the addition of nanosilice, using aggregates of the cantera de Añashuayco de Arequipa
Abstract: The present research work is developed using the experimental study to evaluate concrete elaborated with aggregates from the Añashuayco quarry (Peru), with the addition of Nanosilica containing micro-fine nanoparticles of amorphous silica dioxide (SiO2). Nanosilica has pozzolanic propertie...

A.Ruiz Pico,Á.A. Nanosilica Strength Compression Permeability. Abstract: The present research work is developed using the experimental study to evaluate concrete elaborated with aggregates from the Añashuayco quarry (Peru), with the addition of Nanosilica containing micro-fine nanoparticles of amorphous silica dioxide (SiO2). Nanosilica has pozzolanic properties that upon contact with water reacts with the hydrated cement to form more C-S-H particles (GEL). This reduces the porosity by partially filling the pores to refine the structure, and therefore gives us a higher compressive strength. This study’s recommendation is to implement it into low-rise and low-cost housing construction.The microstructure properties of the cement paste are improved with the addition of nanosilica. Nanoparticles have high specific surface areas, and their surfaces are very active; an intense pozzolanic reaction between nanosilica and CH would accelerate the pozzolanic reactions between SiO2 and water molecules. Therefore, the smaller the pore volume, the higher the compressive strength and water absorption capacity of nanosilica-modified pastes. The pore volume decreased along with the dosage increase of nanosilica. The cement-sand mixture without nanosilica shows a porous structure, after 7 days of curing.info:eu-repo/semantics/openAccessPontificia Universidad Católica de Chile.
